good one Cap'n - but seriously - my research shows that MB antifreeze has a PH of 6.5 whereas NA antifreeze has a PH of 9.5-10.5 which affects the lifespan of plastic parts and hoses. I know that in NA there is no other approved antifreeze other than MB brand. In Europe (where Pentosin is made) there are apparently 6-8 other brands that are approved for use in MB's. Anyone in Europe know if Pentosin is approved.
Thanks
